strange electrical bug

I've been getting a strange electrical glitch on my 01 Z28 and am hoping someone has an idea what it might be.

Since I've had it when I shut it off I can sometimes hear a buzzing discharge noise coming from what sounds like just behind the headlight on/off switch. Like a capacitator discharging.
Lately I've had the interior lights flashing after I shut the car off when I just sit in the car not opening the door or anything. Like it thinks I've opened the door so it is bringing the lights up and down. very strange. If I pull the key out and open and shut the door it will stop.

I've had that "buzzing" sound in my car for the life of the car (currently have 105,000 miles on it). I believe it is normal. Just most people don't sit in their cars after they turn them off in a place quiet enough to hear it. The other occurances are more than likely totally unrelated to the noise. Then again I also have this wierd metallic "ta ting" noise from under the car when I shift into reverse that no one can seem to find as well. This also has done it since the day I bought the car and no problems have arisen from it. Some cars just have gremlins.
